Abstract

This extended abstract presents a natural pointing system using gyroscope MEMS, which could achieve what you pointing at is what you get. It enables screen interaction via physical pointing. The system only needs a phone with built-in gyroscope, camera, and wireless communication, e.g. Wi-Fi and Bluetooth, without any other hardware. To achieve sensing of the screen position where user is physically pointing, we also develop easy calibration methods. The prototype system, called EasyPointer, is built upon iPhone 4/iPod 4. It can serve as a laser pointer, a presentation controller, a game controller, and a drawing pen.
